"dumbbell" blob picker template?


I notice a new “ring” template has been added to blob picker. Would it be possible to add another template type, for “dumbbell” shaped particles, consisting of two gaussian blobs with a given separation?

This would be useful for membrane proteins with a substantial extramembrane domain, where the micelle+TM forms one blob and the extramembrane domain forms the other. Currently, in these cases, the blob picker has a tendency to pick on one domain or the other, resulting in miscentered picks. As it’s quite a common case I think it might be worth adding in a template for this purpose.

I just had an idea on this - what if it was like a multipole expansion?

In this way slightly more complex requirements could be adapted without a lot of different template types.
